Light reflects when it bounces off an object, similar to how a ball bounces off the ground. This phenomenon is what allows us to see the world around us.
Here are some things to know about light reflection:
- Types of reflection: Light reflects in different ways depending on the surface it hits:
- Specular reflection: Light reflects off a smooth surface at the same angle it hit the surface. This is because the reflected light rays travel in the same direction.
- Diffuse reflection: Light reflects off a rough surface in many different directions.
- Specular reflection: Light reflects off a smooth surface at the same angle it hit the surface. This is because the reflected light rays travel in the same direction.
- The law of reflection: The angle of incidence equals the angle of reflection.
- Objects that use reflection: Mirrors, periscopes, and the side mirrors of cars all use reflection.
- How we see things: When light reflects off an object and enters our eyes, it hits the retina and sends an electrical signal to the brain. The brain interprets this signal as an image.
